Laughing my butt off about the holder on the inside of the truck lid. I thought it was for a folding umbrella. Anyway, it works just fine for that. I guess I have owned too many German cars as that is something they would do.

Maybe this question should be in a separate "thread" (I'm new to this forum), yet it relates to the "5.0". Tire pressure. Probably a personal decision for every owner - especially dear to me. Have observed placard numbers [F=33, R=35] and that's what was delivered. I'm wanting to UP each by 2 or 3# based on my preference to easy rolling vs. soft riding. Would enjoy hearing thoughts & experience.

You definitely can up them by 2 or 3 if you prefer that feel and the harder tire. Me personally, I like to drop tires down 2-4psi depending more for a softer smoother ride. Typically it'll burn a little more fuel but I'm not worried about that. Also helps with traction and what not.

On my old little JDM car that's RWD and I mess around with it all the time, I drop the tire pressures down to 24-25psi in the rear.
